Be'. .rnown that l, QHARLEs A. ST-rc'xNEY, of- Sj-t .Paul,, Ramsey county, Minnesota, have inventedcertain new and useful Improvement's; inSaw-Erames, of which the'folwingxisaspeci catio inventionjrelates to saw-frames, and particularly those-lofthe portable type; and

the Fobject; of; the invention is to provide a frame ,ofjsimple butstrong and durable construdtion and-one, that can be easily and quickly secured to' the frameofawagon' or .triuckand as readily removed; r

Other objectsofhe' invention will appear '15 from thefoll0yvi11gcdetailed description.

The inventiontconsists generally in providing ah-saw frammthat is capable of being adjustedslateially;With respect to the wagon or truck frame; 'according to the position of the motivepower onithe-tr'uck.

, Fufithenqthei-nvention consists in provid aifra'm'e having rigid bearings for the sawarbonzland icapable ofibeing secured to the.

- truck-frame or adjusted thereon 2 5 turbingsuch bearings=.

5 is a casting, tubular in form; open at each end and rovided with a fiat surface 6 on one side t at is adapted to fit snugly against the plate 4 and is secured thereto by bolts 7 passing through holes 8 in said casting and in said plate. I prefer to provide a series of these holes in the casting arranged in rows at intervals to allow the saw-frame to be ad-- justed laterally with respect to the truckframe, according'to the position of the engine there'on,'thereby adapting the frame for attachment to truck-frames of different Widths andpermitting the saw-arbor pulley namel.

I S ii'eeificationof was Patent ratenfieamlyagieoe. hpplicationfiled rbmmyz a' eoa. serai' a.24 z,56sl*' ll f I to properlyalined with the: driving pulley of theengine'. :The-open'ends of the tubular casting permit convenient access to the bolts 7 and greatly facilitate the attachment ofthe saweframe to. the truck-frame or their sepa- 121310.11. f

, At each'end of the casting 5, onthe upper side thereof, I provide boxes 9, wherein a saw-arbor 10 is journaled. Ribs or Webs 11 are preferablyformed in the ends of the, cast,-

ing to strengthen it at the point where the bearings are placed. A circularfsaw 12 is mounted on one end of the arbor 'and the other end is provided with a fly-wheel 13 and a pulley 14, driven from the engine, (not? shown,) mounted on the truck-frame. Arms 15 are riveted at oneend toth under side of the castingfi and extend rearwardly therefrom and are provided at -their rearendS with I upright bars 16, that are pivotallysecured to saidarms by bolts 17 A series of holes 18 and 19 in said armsand bars respectively permit their adjustment vertically and also toward and from the rear end of,the trucle frame to vary theposition of the hopper or shelf Whereon the material to be sawed. is placed with respect to the saW IdArms 20 .are bolted to the bars 16 and extend horizontally therefrom, and aresupporjted attheir outer ends by braces 21. .Bars, 16 are also connected by cross-bars 22, that are 'prefer -f ably arranged between, the arriis,20., All

these arms and bars are preferably made of angle-bar on account-of its strength and rigiditycompared with its Weight. Theupp er ends of the bars16 and the bars 22 are -pro, vided with a plank 23 and form theg bottom and one sidewall of a hopper ,Wherein the cord-Wood sticks usually sawed with this type of machine are placed. Flat braces 24 connect the bars 16 and are secured together at: their points of intersection by abolt25. .A sleeve 26 is mounted onasaid bolt between the b arsnandtserves to spread their middle portions and give to the bars a truss eflfect that aids materially in strengthening and staying the supports 16 and the hop er carried thereby. A chain 27, conneote to the casting 5 and to the cross-bar 22, limits the outward movement of the hopper.

The manner ofusing the saw-frame is as follows: The casting having been bolted on the end of the wagon-truck in the desired position to bring the saw-arbor pulley in proper alinement with the engine-pulley, the operator will. start the-saw, and then placing the stick of cord-wood or piece of timber that it may be desired 'tosaw in the hopper swings it in toward the saw in the Well-known 'way. The adj ustability of'the bar 16 will allow the position of the hopper to be changed with respect to the saw and enable the operator to kind or size of wood that is being sawed. The saw-arbor being mounted upon the casting can be easily and quickly attached to a truck frame, and no fitting or adjustment will be required other than to place the casting on the end of the frame, so that the saw-arbor pulley will be properly alined 'with the drivingulley.

T e use of the angle and channel bars insures a very strong and rigid construction for i the frame, the arms being of such strength that when they strike an obstruction in moving the machine from place to lace the entire rear end of the truck and mine will be lifted, or if it is desirable to prevent in a measure the contact of the arms 15 with an obstruction the lower bolts securing the cast ing- 5 to the truck-frame can be loosened, so that the frame will swin' upwardly and clear any obstacle in its patli.

I claim as my inventioi1- 1. The combination, with a truck-frame, of i a casting tubular in form, havin "a flat surface on one side and means securing it tothe end of said truck-frame, boxes mounted on said casting, a saw-arbor journaled in said boxes and having a saw, and said casting having openings 'topermit convenient access to the flattened side-thereof and to the said securing means. 7 p p 2. The combination, with a truck-frame, of a casting tubular in form, having openings and a flat surface on one side provided with a series; of holes. arran ed in rowsv at intervals, bolts passing throug said holes and through the end of said truck-frame and accessible through said openings, and whereby said castin is rendered longitudinally adjustable on sai frame, and a.sawarbor having a saw and journaled on said casting, substantially as described. 3. The combination with a suitable frame, of a hollow casting having ,a flat surface on one side andmea'ns for securing it to said frame and permitting transverse adjustment thereon, boxes mounted on said casing, and

a saw-arbor 3ournaled m sa1d boxes, and said casting having openings to allow. access to sa1d securing means.

4.- The'combination with a frame, of a tubular casting, means for detachably securing said casting to said frame, boxes mountedon said casting, and a saw-arbor journaled in said boxes, and said casting'having openings -to allow access to saidsecurin means. easily and quickly adapt the frame to the 5. The combination with t e truck-frame having channel-bar side rails, of a plate con-v necting the ends thereof in' a vertical plane, a su port having a flat surface to fit the vertical surfaceof said plate, means for securing said support and said plate together, a sawarbor mounted on said support, and an oscillating hopper provided in the rear of said support, substantially as described.

6'. The. combination with the parallel channel-bars 3, of a plate 4 connecting their. rear ends and provided with vertical rows of holes,-

a casting secured to said plate and adjustabletransversely with respect to said channelbars, a saw-arbor journaled on said casting, and an oscillating hopper supported in the rear of said casting.

7. The combination with a truck-frame, of a saw-frame secured thereon and comprising a casting, a saw-arbor j ournaled thereon, arms secured at one end to said casting and depending rearwardly therefrom and pro ing interio'rly-arranged strengthening-ribs, a

saw-arbor journaled on said casting, and an oscillating hopper supported by said casting,

and said casting having openings through which access may be ha t stantiallyas described.

9. The combination with a frame, of 8 til bular casting, means for securing said casting to said frame, and said means being accessi-- ing, a saw-ar or joumaled on said casting,

and an oscillating hopper supported by said 1 casting.

In witness whereof I havehereunto set my hand this 17th day of February, 1905;
